How to debug a JSP tomcat service using eclipse?

Question

I would like to debug my separately running JSP/Struts/Tomcat/Hibernate application stack using the Eclipse IDE debugger. How do I setup the java JVM and eclipse so that I can s

Answer 1

Follow these steps:

1. Add the following arguments to the java command that is used to launch Tomcat (on Windows, I think this is in TOMCAT\bin\catalina.bat)

   -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

2. In Eclipse, create a 'Remote Java Application' debug configuration and set the port to 8787 and the host to the name (or IP address) of the machine where Tomcat is running. If Tomcat is running on the same machine as Eclipse, use 'localhost'.

3. In the 'source' tab of the debug configuration, add any projects that you want to debug into

4. Start Tomcat

5. Launch the debug configuration you created in step 2

6. Eclipse should now stop at any breakpoints that you've set in the projects you added in step 3.

Notes:

• You can change the port to any other available port if for some reason you can't use 8787
• If you want Tomcat to wait for the remote debugger to start, use 'suspend=n' in the command above to 'suspend=y'
